ITEM-GIPHER PRINTING MEANS FOR CALCULATING-GENES.

Original application filed October 16,

To all inhomit may concern,

Be it known that I, EDwixL. KELLER, a citizen of the United States, formerly residing at the city of St. Louis, State of Missouri, but, now residing atthe city of Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in ItemCipl1er-Print' ing Means for Calculating-Machines, (the present application being one divided out of that filed by me October 16, 1911, Serial No. 654,982,) of which the following is a specification.

. This application is a division and continuation of one filed .by me October 16, 1911,

Serial No. 65%,982. The present invention relates to lmprove ments in calculating machines and is more I especially applicable to calculating machines sition, without requiring operation, either manual or otherwise, pieces.

In the accompanying drawings forming part of this specification, in which like numof the sectors or finger bers of reference denote like parts wherever they occur, Figure 1 is a detailed view of a portion of one of the item printing sectors and the associated parts, which control and actuate the item cipher-printing means and, also, control and actuate the accumulator;

and Fig. 2 is a sectional view, on an en larged scale, on the line 22, Fig. 1.

The present embodiment of this invention is, previously stated, applicable particularly to calculating machines of the type disclosed in the above-mentioned application, Serial No. 618,655, and hence reference is here made to that application for a dis- Specification of Letters Patent.

operation of the machine in general and such parts or elements of the machine as control 9 or actuate the item printing means and, also, i

msm.

The mechanism for printing the items and transmitting the same to the-accumulator to be totalized is shown in the the several printing sectors or finger pieces. which are mounted to'turn independently and concentrically on a shaft 1, each sector or finger piece having a disklike hub 2 formed on a portion of its circumference with atoothed sector 3 and on another portion of its circumference with the item-printing type 4: bearing consecutively arranged numerals, any one of which may be broughtto the printing point by appropriate rotation of the sector. The toothed-sector 3 cooperates with a longitudinally reciprocatory rack bar 5, there being one of these rack bars for eachsector.

The printing portion of each sector or finger piece is provided, according to the present invention, with'means whereby the setting of one sector to bring a selected numeral thereon to printing position will automatically set the printing portions of all sectors to the right thereof, in condition to print ciphers, without requiring operation of such sectors, either manually-or otherwise to accomplish this result, To this end, the disk-like hub of each sector is provided with a shiftable bar 6, which is slidably guided by grooves 7 in the sector-hub, and

the outer/ end of this bar bears a zero type face 8, which is normally below or within the arc of the type faces a and is yieldably retained in such position by the retracting spring 9, which acts on the bar 6, but this zero type face is capable of beingbrough't into arcuate alinement with the other type characters by a shifting movement of the bar 6, whereby the zero type facej' is brought into printing position.

The reciprocatory bar 5 is formed with a longitudinally-extending slot 10, and the forward end of this slot has an enlargement 11, an inclined or cam surface 12 being between the narrower portion of the slot and its enlargement. A plate 1321s mounted at the left-hand side ofeach rack bar, the front end of each plate being slotted and guided by a cross-rod 1 4. and each plate is normally held in forward position by a tension spring 15. Each plate 13 has an upwardly andrearwardly sloping incline 16,

bar 6 bears under the influence of its spring J. and each plate is, also, formed with a slot 1?,which forms a shoulder 18. A set of independently movable arms 19, of a number correspoi'iding to the number of rack bars and plates, are pivotally mounted on :1 cross-bar 20, the latter having its ends fitted in longitudinal slots 21 in the side plates 22 to permit the cross-bar and the arms 19 thereon to shift bodily in a forward and rearward direction, such parts, however, being returned to and held in normal position by the tension springs 23 attached to depending lugs on the arms. The free end of each arm 19 is provided with a laterallyturned and downwardly-inclined finger 24, which extends through the slot enlargement 1.1 of the rack bar and the slot 17 of the plate 13, the finger of each arm engaging beneath or-underlyingthe finger of the next adjacent arm to the right, as shown clearly in Fig. 2? By this arrangement, rotation .of asector to bring a selected numeral to printing position will cause its cooperating rack bar 5 to move toward the right, Fig. 1, and during such movement the cam or inclined surface 12 will operate upon the respective finger 2st to elevate it, and lifting of one of these fingers 24 causes lifting of the remaining fingers to the right, the remaining fingers .being thereby presented to the respective shoulders 18, and forward movement of the cross-bar 20 will cause the raised fingers to abut against the shoulders 18 and thereby shift the corresponding plates 13 forwardly or toward the right in Fig. 1. the inclined surface 16 of each plate operating upon the respective bar 6 bearing thereon and causing the latter to shift in a manner to bring its zero type face 8 into printing position. Operation of the crossbar 20 is effected in the usual manner by the main operating element (not shown) of the calculating machine,,to which it is suitably connected. No ciphers will be'printed to the left of the set sector, as the finger 24 of each arm 19 is capable of set-ting fingers to the right thereof, the zero type faces on the sectors to the left, therefore, remaining depressed below the printing line.

The forward end of each plate 13 is guided relatively to its respective rack bar by a pin 25 on the plate which operates freely in a longitudinal slot 26 in the rack bar, it being, of course, understood that the forward ends of the rack bars 5 and the cooperating plates 13 are supported in the usual manner in the entrance of the accumulator (not shown) and the upper forward edge, each rack bar being provided with a rack 27- to cooperate with its respective printing wheel of the accumulator.

The operation of the mechanism is as follows; The entering-of the items is accom plishcil in the same manner as described-in that is to say, by depressing and rotating the finger pieces or sectors, and when each finger piece or sector is depressed or rotated, the rack bar 5, which is operatively' connected thereto, moves forwardly into the accumulator. The forward movement of a rack bar 5 by manipulation of its respective sector causes the inclined or cam surface 12 on the rack bar to ride beneath the corresponding finger 2%, thereby raising such finger, and the linger so raised will act simultaneously to raise all fingers to the right thereof-and each of the raised fingers will be then positioned opposite to the corresponding shoulder 18 on the respective plates 13, and, hence when the cross-oar 20 is moved forwardly. or toward the right, Fig. 1, all the raised fingers will abut against the corresponding shoulders 18, with the result that the respective plates l-fare, also. moved forwardly, causing the inclined surfaces 16 thereon to operate upon and fOl't'Q upwardly the bars 6 bearing the zero type faces 8. the zero type faces being thereby hrough to printing position.

I claim:

In a calculating machine, the combination, with a plurality of printing devices each embodying an endwise movable b'a-r bearing a cipher printing type face, and means acting upon said bar for normally holding its upper type face in non-printing position. of means operative when one of said devices is actuated to move the bars of all devices to the right thereof in one direction, for setting the cipher type faces of those bars in printing position.
